AUTO switch Turns the switch indicator lamp and "AUTO" indicator on the display ON, and then front air condition-
ing system becomes the following state.
Air inlet: Automatic control
Air outlet: Automatic control
Blower fan: Automatic control
Compressor: ON
A/C switch Turns the compressor control (switch indicator) between ON
⇔ OFF each time while front blower fan
is activated.
NOTE:
When front blower fan is OFF, the compressor control cannot be activated.
When the compressor control (switch indicator) is in the OFF position, air inlet is fresh air intake (FRE).
Defroster (DEF) switch Turns DEF mode (switch indicator) between ON
⇔ OFF each time.
When DEF switch is pressed while front air conditioning system is in the ON position.
When DEF mode is turned ON, front air conditioning system becomes the following state.
- Air inlet: Fresh air intake
- Air outlet: DEF
- Blower fan: Automatic control (If fan speed other than AUTO is selected before pressing DEF switch, fan speed is manual control.)
- Compressor: ON
When DEF mode is turned OFF, front air conditioning system state returns to the previous state before DEF mode is selected. But, the following state is continued.
- Air inlet: Fresh air intake
- Compressor: ON When DEF switch is pressed while front air conditioning system is in the OFF position.
When DEF mode is turned ON, front air conditioning system becomes the following state.
- Air inlet: Fresh air intake
- Air outlet: DEF
- Blower fan: Automatic control
- Compressor: ON
When DEF mode is turned OFF, entire front air conditioning system is set to auto mode.
NOTE:
When DEF mode turns ON while front air conditioning system is in automatic control (“AUTO” is indi-
cated), automatic control is released (“AUTO” turns OFF).
DUAL switch Turns left and right ventilation temperature separately control (switch indicator) between ON
⇔
OFF each time.
When DUAL switch indicator is ON, the driver side and passenger side temperatures can each be set independently.
When DUAL switch indicator is OFF, the driver side outlet and setting temperature is applied to both sides.
Left and right ventilation temperature separately control is cancelled by turning the DEF mode ON.
NOTE:
When front air conditioning system is in the OFF position, left and right ventilation temperature sepa-
rately control can be selected only while front air conditioning system state (when MODE switch is
pressed) is indicated on the display.
Fan switch (UP/DOWN) Blower fan speed is manually controlled with these switches. Seven speeds are available for manual
control (as shown on the display screen)
NOTE:
When fan switch is pressed while front air conditioning system is in OFF, front air conditioning sys-
tem is activated. (Compressor control state returns to the previous state before front air condition-
ing system OFF.)
When fan switch is pressed while front air conditioning system is in automatic control (“AUTO” is
indicated), automatic control is released (“AUTO” turns OFF).
MODE switch Selects air outlet sequentially from VENT
⇒ B/L ⇒ FOOT ⇒ D/F ⇒ VENT each time.
NOTE:
When front air conditioning system is in the OFF position, air outlet can be selected.
When MODE switch is pressed while front air conditioning system is in automatic control (“AUTO” is indicated), automatic control is released (“AUTO” turns OFF).
OFF switch Turns front air conditioning system OFF.
When front air conditioning system turns OFF, air inlet and air outlet become the automatic control.
